Long means you believe in the ultimate return on a long term investment. You ride the ups and downs through thick and thin because you ultimately believe you will make money.

Not all "longs" are equal, and I'm not talking about how heavily invested one is. We all have our due diligence on the science, finances, opinion of management, and competitive landscape. Over time, biases develop and I'm most certainly guilty of being hardened by Nader's missteps, missed timelines, etc. The "New Longs" don't have the experience of having watched the "any day" or "end of the month" statements that were dishonest at best. In my personal experience, those negative incidents are balanced out by a better understanding of the amazing and still evolving science. I can argue for or against the ultimate probability of success, but at the end of the day, my money is where it is TODAY, subject to change overnight.
